Abstract (en)

In a disc brake the application of the brake is initiated by angular movement of at least one pressure plate with respect to reaction member to cause the pressure plate to move axially into engagement with a friction disc which, in turn, is urged into engagement with a surface in a stationary housing. The angular movement is effected hydraulically by an actuator comprising a piston (8) working in a bore (7) of a cylinder (5), the axis of which is substantially at right angles to that of the brake. The piston (8) acts on a thrust member (13) having a part-spherical inner surface (14), co-operating with a complementary surface on the inner end of an axially split collet (15) and the thrust member (13) is slidable in a transverse direction with respect to the piston (8). The collet (15) is associated with a pull-rod (23) passing through the actuator with a substantial clearance, the inner end of the pull-rod (21) being pivotally coupled to a lug on the pressure plates, and the outer end being adapted for connection to a hand lever (21) by means of which the pull-rod (23) can be moved in a brake-applying direction.
